In bacterial extracts both phospho enol pyruvate (the physiological phosphoryl donor of the PTS) as well as ATP can phosphorylate III Glc . The ATP-catalyzed reaction is dependent on phospho enol pyruvate synthase, however, and is due to prior conversion of ATP to phospho enol pyruvate. The ...
Pathways involved in the conversion of phosphoenolpyruvate (PEP) to pyruvate, the final step in glycolysis, were investigated after transfer of stationary-... M Nagano,A Hachiya,H Ashihara - 《Zeitschrift Für Naturforschung C》 被引量: 79发表: 1994年 Metabolic impairment and membrane abnormality ...
The reactions of phosphoglycerate mutase, enolase, and pyruvate kinase are coupled together for the conversion of PGA to pyruvate. The production of pyruvate is done with careful attention to detail, owing to the possibility of excessive exchange with medium protons in the pyruvate kinase step ...
Phosphoenolpyruvate (PEP) mutase catalyzes the conversion of phosphoenolpyruvate to phosphonopyruvate, the initial step in the formation of many naturally occurring phosphonate compounds. The phosphonate compound 2-aminoethylphosphonate is present as a component of complex carbohydrates on the surface membrane...
This enzyme catalyzes the conversion of pyruvate and ATP to phosphoenolpyruvate (PEP), AMP, and phosphate and is thought to function in gluconeogenesis. PpsA has a subunit molecular mass of 92 kDa and contains one calcium and one phosphorus atom per subunit. The active form has a molecular ...
various periods of exposure to anoxic seawater and incubated under nitrogen in the presence of metabolic inhibitors (aminooxyacetate, iodoacetate, 3-mercaptopicolinate) and UL-14C substrates, in order to examine the redirection of glycolytic flux from pyruvate kinase to phosphoenolpyruvate carboxykinase....
Lactate dehydrogenase (LDH) typically facilitates the conversion of pyruvate into lactate and acetyl-CoA in other Babesia species (Yu et al. 2021), but LDH has not been identified in B. gibsoni, indicating the absence of this metabolic pathway or the involvement of another enzyme in this ...
The phospho enzyme is converted to the dephospho form by a phospho-protein phosphatase, the activity of which is also regulated by cAMP-dependent protein kinase (Figure 12-4). Sign in to download full-size image Figure 12-4. Action of glucagon on the liver pyruvate kinase (PK) via the ...
1. The properties of pyruvate kinase and, if present, phosphoenolpyruvate carboxykinase from the muscles of the sea anemone, scallop, oyster, crab, lobster and frog were investigated. 2. In general, the properties of pyruvate kinase from all muscles were similar, except for those of the enzyme...
